In the Curve Channels panel:
|For Process Inks|
To use the same transfer curve for all CMYK process inks, select One channel for CMYK.
To use the same transfer curve for all inks of an extended process ink set, select One channel for CMYK+. This provides the same transfer curve for CMYK and Red, Orange, Green, Blue, Purple and Violet inks, if present in your ink set.
|To use a separate transfer curve channel for each CMYK process ink, select Separate channels for CMYK.|
To use a separate transfer curve channel for each ink of an extended process ink set, choose the selection that contains your extended process ink set, for example, Separate Channels for CMYKOGV if your process inks are C, M, Y, K, O G and V in any sequence. If a selection for your ink set does not appear:
|In the Spot Inks table||Select the Default curve channel to use for undeclared spot inks.|
Add any spot inks for which you want custom curve channels. See Adding a spot ink to a print transfer curve if applicable.
To create a Transfer Curve, you can use one of the following methods: Tint In/Output Points, Custom Shape, or Imported.
|To create a Transfer Curve from a set of input and output values|
Select Curve Origin: Tint In/Out Points (default selection) and enter the desired Tint Out value for each corresponding Tint In value.
|To create a Transfer Curve using a Custom Shape|
To create Transfer Curves for Flexo Press Device Types:
When you select Device Type: Flexographic Press an additional curve creation method-- Curve Origin: Flexcel NX Preset --becomes active. This allows you to create custom flexo adjustment curves that have been optimized for use with Miraclon Flexcel NX plates.
Use the arrows to adjust the amount of Midtone Tone Value Increase measured with a test print from a Flexcel NX plate. The resulting curve will compensate for the entered amount of Midtone gain.
To create MinDot Bump or Cutoff curves in conjunction with any Curve Origin method:
|To use existing curve data from Harmony|
Click Curve Origin: Imported and click Imported to import the file.
In ColorFlow 8.4 and later, to facilitate the migration of Harmony curves to ColorFlow, you can convert a Harmony OneCurve curve to a print transfer curve with Curve Channels: Process Inks value One channel for CMYK selected, so that you can continue to work with a single curve channel in ColorFlow.
